A technique used in drawing and linear forms of printmaking, in which lines are placed in parallel series to darken the value of an area. Cross-hatching is drawing one set of hatchings over another in a different direction so that the lines cross.

Repeated strokes of an art tool producing clustered lines (usually parallel) that create values. In cross -hatching similar lines pass over the hatched lines, following a different direction and usually resulting in darker values.

This term is used in drawing to indicate the use of parallel strokes or lines placed close together to suggest shadow. Sometimes this term is also used in painting indicating separate strokes of the brush.

One of the basic ways an artist builds up form through purely linear means: the artist makes closely spaced parallel lines with a drawing instrument, usually pen and ink or chalk, in order to create areas of tone. In Cross-Hatching, the artist adds another set of lines in the opposite direction, creating a grid-like, diamond-shaped pattern.

Creating tonal or shading effects with closely spaced parallel lines. When more such lines are placed at an angle across the first, it is called cross-hatching. Artists use this technique, varying the size, closeness and other qualities of the lines, most commonly in drawing, linear painting, engraving, and ethnic.

and cross-hatching – In drawing, using parallel lines of varying closeness to create shading. Cross- hatching is drawing in lines at an angle over the initial lines. See the Drawing and Sketching or Pen and Ink forums.

Hatching (hachure in French) and cross-hatching are artistic techniques used to create tonal or shading effects by drawing (or painting or scribing) closely spaced parallel lines. When lines are placed at an angle to one another, it is called cross-hatching.

A multi-step process, first described for C. elegans by Singh and Sulston (1978), by which the developing embryo makes an opening in the egg shell and exits this covering. Secretions from pharyngeal glands may promote he gradual weakening of the eggshell, which becomes visibly softer and more pliable in the hour just before eclosion. Once weakened, the motions of the three-fold embryo cause distortions of the whole shell and eventually the eggshell ruptures, allowing the new L1 larva to emerge from the broken shell. See Eclosion

Opening of the zona (outer shell of the egg) due to expansion of the volume of the embryo through repeated cleavage. It occurs a few days after the embryo arrives or is deposited in the uterus and immediately precedes implantation (see also ASSISTED HATCHING).

A hatching is when the firelizard or dragon eggs are ready to break free from their eggs. They are hungry and think of nothing else as the leave thier eggs. This is the moment when they may be impressed by a human.
